Rearview mirror adjustable in two planes

Abstract

A rearview mirror for vehicles which is adjustable in two planes and has a mirror housing accommodating the mirror glass, a universal mounting for adjustment of the mirror, and a mounting housing accommodating an adjustment drive mechanism. Two shafts are connected to the adjustment drive mechanism, the shafts being driven directly by the adjustment drive mechanism and being rotatable independently of each other. One of the shafts is connected to the mirror housing so that when that shaft is driven, the mirror is swivelled relative to the housing and the other shaft is rigidly mounted on the framework of the vehicle so that when it is driven the housing mechanism together with the mirror housing is swivelled about the last mentioned shaft.

I claim: 
     
       1. In a rearview-mirror for vehicles which is adjustable in two planes and includes a mirror housing accommodating the mirror glass therein, the mirror housing being supported for swivel movement relative to a support to be rigidly connected to a vehicle, the mirror being adjustable by a universal joint having a pair of joint shafts and a drive housing incorporating adjusting drives connected to the pair of joint shafts, the joint shafts being driven directly by the adjusting drives and being relatively independently rotatable; the improvement comprising means connecting a first joint shaft of said pair of joint shafts to the mirror housing whereby when said first joint shaft is driven the mirror housing will be swivelled relative to the drive housing, and means connecting a second joint shaft of said pair of joint shafts of the universal joint to said support such that when said second joint shaft is driven the drive housing will be swivelled together with the mirror housing relative to the support. 
     
     
       2. A mirror according to claim 1 in which said shafts extend completely through the mounting housing for the drive mechanism. 
     
     
       3. A mirror according to claim 1 in which one of said shafts is divided into two parts, one of which is hollow and which accommodates electrical connections to motors forming part of the adjusting drives.
